Alpinia

Alpinia is a genus in the Zingiberaceae or ginger family. Most of the genus is tropical and sensitive to frost, though several species are root hardy to at least zone 8. Since most species bloom terminally on older stems if growth is killed by freezing, there will be no flowers. Most species have highly aromatic foliage which emerge from pseudostems which can be anywhere between 6" to 25' (15 cm to 8 m) tall and arise from fleshy rhizomes.
